[aprssig] I'm still waiting for...

But this is *not* the same - sure, I have my gripes about the DSTAR 
architecture, the way the protocol is implemented, the awful 
documentation - but none of that is a huge deal.  Using the AMBE codec 
as a required part of that on-air standard IS a big deal, and it's more 
a legal issue than a technical gripe.

As others have pointed out here, if you were to come up with your own 
implementation of the AMBE codec and use it on the air for DSTAR 
compatibility, DVS would almost undoubtedly sue the pants off you - and 
not just for not paying them their licensing fee, but probably for 
opening the door to east Asian IP pirates who might use your code to 
make knock-off AMBE codecs for commercial products.

What OTHER on-air amateur radio protocol or modulation technique, past 
or present, are you absolutely NOT allowed to duplicate entirely by 
yourself?  I'm not sure even Pactor III falls into that category, and at 
least it's not presented as an open standard.
